Some of you may remember the unique little squirrels I discovered when we first moved here… little black squirrels with partial or completely red tails.

In truth, I haven’t seen them for quite a while now. In fact, it’s just been solid black squirrels this summer. The last grey one I saw was in spring.

But then this little one showed up.

Not just a full red tail – but a red streak from nose to butt!

And as cool as it is, it’s not magic – there is an explanation. Here’s the science: Black squirrels sometimes have red or rusty-colored patches of fur due to a mix of genetics and natural coat changes. Black squirriels are actually a melanistic form of the gray squirrels (so grey and black squirrels are the same species) but if they carry genes for lighter or reddish coloring, those can still show through in areas where the black pigment is weaker. Sun exposure and seasonal molting can also affect their coat, causing the fur to fade or grow back with brownish or reddish tones. It’s a completely natural variation. Because nature is amazing!
